No need to piss off Mavericks.
Yeah, that would be cheeky.

I don't think we actually get the 5% bonus at all if we fortify on the spot. It's easy to check this in Buffy though.
Either way I say go the path of Sir Robin. The spot we need to protect is where we're going to settle. So let's move there, via the copper to avoid a conflict on the way. From the settling site we'll be in a jungle, and likely across a river from the barb we can see now. As I've said before, we don't really benefit even from defeating the barbarian at the moment, and we certainly don't benefit from losing to it.
We definitely get the 5% fortify bonus if we don't move him this turn, I'm certain of this.
Well, you need to learn to be less certain of things when all they're based on is your own intuition/opinion then. I just did the experiment, and the combat odds are:
* Without fortifying, 2.5 vs 2 at 74.9% odds for us to win
* Fortifying this turn, 2.5 vs 2 at 74.9% odds for us to win
* Across a river into jungle, 3.5 vs 2 at 96.7% odds for us to win
You can try it yourself, find a hill, move a warrior onto it, worldbuild a barbarian onto it the next turn, press fortify, and check the combat log.
So, there's no point fortifying this turn, we don't get the bonus before the barbs have their turn.
It's a moot point anyway, because we don't want to fight this turn regardless. NE to copper, followed by NW to planned settling location is still my vote.
Didn't test in a simultaneous turns game.
